Abstract:

A sugar-based functional monomer containing double bond was synthesized by the reaction of D-glucose, hydroxylethyl acrylate and 1,4-butanediamine. The as-prepared compound was confirmed by Fourier transform infrared spectroscopy(FTIR) and proton nuclear magnetic resonance spectroscopy(1H NMR). The unsaturated sugar monomer was grafted onto the surface of polyurethane(PU) films by UV-induced grafting polymerization. The surface grafting polymerization was confirmed by FTIR in the attenuated total reflection mode(ATR-FTIR). Water contact angle measurement and platelet adhesion were used to study the hydrophilicity and hemocompatibility of the modified PU films, respectively. It is found that the contact angle of modified PU films decreases from 86° to 45°, and the amount of platelet adhesion is reduced from 14.36×103 cells/mm2 to 2.57×103 cells/mm2. The hydrophilicity of the modified PU films is obviously enhanced and a more hemocompatible interface can be obtained between the film and the biomolecules.
